Despite the number of kingdoms in the deep sea being smaller than in coastal systems because of the absence of photoautotrophic taxa, there is no deep-sea area or station where the total biodiversity (i.e., the biodiversity of all forms of life ranging from Bacteria and Archaea to Megafauna) has been censused.
A large proportion of the global biodiversity, however, consists of forms or ecotypes of species not fully reproductively isolated (Seehausen 2000).
Eukaryotic cells appear to have evolved between 2.7 and 1.4 billion years ago, multicellular animals are thought to have developed about 800 700 million years ago, and the biodiversity of modern life forms, including the first known chordate, is known to have evolved by about 500 million years ago with the Cambrian explosion (Gould 1990; Meyerowitz 2002).
These are the farmers who have grown 54 seed banks across 16 Indian states to restore agricultural biodiversity in the form of 2,000 varieties of rice.
Using the Southampton, UK, as a case study, this paper estimates the public's perceived value of green walls to urban biodiversity, in the form of their willingness to pay (WTP).
This can be seen as the basis for the expansion of forms of life, that is, for biodiversity.
Knowledge gained in recent decades confirms this assessment and shows that gene regulatory factors play a central role in the evolution of biodiversity and the generation of form (reviewed in ).
Coral reefs are hotspots of oceanic biodiversity, forming the foundation of ecosystems that are important both ecologically and for their direct practical impacts on humans.
Biodiversity should form part of not only European nature policy but also other policies, such as fisheries, agriculture and regional policy.
This paper forms part of a broader overview of biodiversity of marine life in the Gulf of Maine area (GoMA), facilitated by the GoMA Census of Marine Life program.
Exotic biodiversity forms the basis of most agricultural systems worldwide, including crop and livestock species, as well as the many other species that have benefitted from human activities.
